Hi Brad,
ITK_USE_SYSTEM_GDCM is not an option for me. I am given an already
compiled ITK version (statically if that matters).
I understand now the need for GDCM deep down in the build settings. I
think I should be able to tweak `include(${ITK_USE_FILE})` to remove
automatic io factory registration and drop "*GDCM*" from
${ITK_LIBRARIES}.
Will let you know how it goes. Thanks for your help.
